Instead of having a tranparent background like this:

enter image description here GNOME Activities Overview is having a solid black background. How can I get the transparency?

I figured it out. It seems to be a bug of the proprietary fglrx driver. Some people recommend turning off the Have file manager handle the desktop in the GNOME Tweak Tool, but it didn't work for me, so I changed to using the open source ATI driver instead. It's working fine now.

It happens to me with Intel open-source driver too. So it's not restricted to fglrx. – Rmano Aug 11 '13 at 8:39

Well it may be something that you can enable via Ubuntu Tweak, I managed to get my top bar to be transparent on Ubuntu Tweak but I'm on the Unity graphical interface so UTweak may not be compatible with GNOME for all I know.

But anyway, heres the link to the Ubuntu Tweak site:

hope this works, if it doesn't then sorry

Happy Ubuntuing =D
